How does geocaching work? I'm glad you asked!
- Go to geocaching.com and get the GPS coordinates of a "cache" near you.
- Find the cache. We use the iPhone's GPS, pictured below.
- The cache usually a waterproof box. Inside is a logbook where you sign your name.
- Sometimes the box has little trinkets -- toys or coins or such. You can take a trinket if you leave another trinket in its place.
